In the year 1816 there was a great fight between the two factions, in which the easterners gained the day. Ali Balli, a western sheikh, went to Egypt and described to the Government the independent state of Siwa and the condition of anarchy prevalent there. In 1820 Mohammed Ali invaded the Sudan. In order to protect his western flank he sent a force of 1300 men, with some cannon, commanded by Hassein Bey Shemishera, one of his generals, against the fanatical population of Siwa. They crossed the desert via Wadi Natrun and the oasis of Gara. A few of the western faction welcomed the army, but most of the population prepared to fight. After a desperate battle, lasting for several hours, the Siwans were severely beaten, and from that date Siwa was permanently secured to Egypt. The Turks entered the town, seized the principal men, and in course of time some sixty of the notables were executed by Hassein Bey, who punished by death on the least suspicion of rebellion or revolt. A tribute was imposed on Siwa, and Sheikh Ali Balli was made omda, supported by the Turks. After some time Hassein Bey and the army returned to Egypt. The Siwans promptly refused to pay tribute, so in 1827 Hassein Bey returned with a force of 800 men, occupied the town after a brief contest, executed eighteen of the notables, confiscated their property, but paid the widows of the unfortunate men ten pounds each as full compensation for the life of a Siwan notable. He also banished twenty of the sheikhs, increased the tribute, and appointed a Turkish officer as Governor of Siwa, with a small force. Under Hassein Bey the Siwans suffered considerably. He seized their money, slaves, dates and silver ornaments, which he sent to his home in Egypt. He built the first “Markaz”—Government Office—whose ruins stand behind the Kasr Hassuna, the present District Officer’s house, where I lived. During the nineteenth century several Europeans visited Siwa, but they met with no encouragement and were in most cases badly treated. One of them, Butin, a French colonel, carried on his camels a collapsible boat in which he hoped to reach the island on the salt lake of Arashieh, which according to legends contained fabulous treasure and the sword and seal of Mohammed. He managed to bring the boat to Siwa, but the natives refused to let him embark. These early travellers all mention the subterranean passages connecting Aghourmi and Omm Beyda, also between Siwa town and the Hill of the Dead. The natives described these passages as having “biute”—houses—or possibly burying spaces, opening out on either side. The entrances have now in all cases been blocked up by stones and rubbish, but with a little labour they could easily be excavated. Several old men in Siwa know the exact position of the entrances to these passages, which I have seen myself.
